RAID CCR TEC
Get personalised RAID rebreather training with Stuart Girdler.
Train on leading rebreather units with RAID’s modern, ISO-aligned closed-circuit training system.
RAID CCR Rebreather Training
Closed-circuit rebreathers offer exceptional precision, longer dive duration, reduced gas consumption, and unparalleled efficiency at depth. But mastering CCR requires structured training, discipline, and a deep understanding of equipment, emergency protocols, and buoyancy control.
At Diving Disciplines, Stuart Girdler delivers RAID’s full CCR Tec pathway with a focus on operational capability, advanced safety systems, and real-world diver development. Whether you’re new to rebreathers or progressing to deep mixed-gas CCR, Stuart provides expert guidance built on decades of technical experience.
What CCR Tec Courses Cover:
Advanced gas planning & decompression modelling
Expedition-level buoyancy, trim, and propulsion
Team protocols & situational control
Deep-water emergency & bailout preparation
RAID CCR Reboot
Refresher for certified CCR divers requiring tune-ups, skill renewal, or updated RAID protocols.
RAID CCR Diver (40m)
Entry-level CCR training covering bailout skills, emergency preparedness, and non-decompression closed-circuit diving to 40 metres.
RAID CCR Deco Diver (40m)
Introduce staged decompression, bailout planning, and advanced ascent strategies using your CCR to 40 metres.
RAID CCR Limited Trimix (45m)
Mixed-gas decompression CCR training requiring efficient gas-switch logic, safe deep bailout strategies, and supported helium use.
RAID CCR Normoxic Trimix (60m)
Deep mixed-gas CCR training using normoxic trimix, extended decompression, and controlled multi-gas bailout planning.
RAID CCR Hypoxic Trimix (80/100m)
Advanced CCR mixed-gas decompression training for dives to 80–100 metres using hypoxic trimix and multi-stage contingency planning.
RAID CCR UNIT-SPECIFIC TRAINING
For divers progressing beyond the core CCR pathway or seeking specialised configuration skills, Stuart offers training tailored to specific units and platforms:
Dive JJ-CCR
JJ-CCR specific training, workflows, and bailout procedures for divers transitioning to or progressing on the JJ unit.
Dive Liberty Sidemount
Liberty Sidemount CCR training for divers seeking profile efficiency, redundancy, and advanced mobility in cave or wreck scenarios.
Dive Liberty Backmount
Backmount Liberty CCR training focusing on deep-water operational performance and integrated bailout strategies.
WHY TRAIN CCR TEC WITH STUART GIRDLER?
Closed-circuit rebreather diving demands absolute discipline, deep situational awareness, and an ability to manage complex systems under pressure. With decades of expedition experience, technical diving leadership, and instructor-trainer credentials, Stuart Girdler delivers CCR Tec training that is structured, precise, and built on real-world capability, not box-ticking.
With small class ratios, uncompromising safety standards, and a focus on operational consistency, you develop the confidence, control, and technical maturity needed to dive deeper, longer, and with greater efficiency.
What You Will Master:
Loop Control & Gas Management: Develop disciplined loop management, PO₂ tracking, bailout strategy planning, and safe use of multiple gas set-points in varying environments.
CCR Configuration & Readiness: Gain expert-level system understanding, pre-dive checks, bailout configuration planning, and in-water competency across recreational and mixed-gas CCR units.
Emergency Preparedness: Practise high-stress bailout drills, fault identification, sensor deviation responses, and real-world emergency scenarios specific to CCR.
Buoyancy, Trim & Stability: Achieve the precise control expected of RAID CCR divers—stable ascents/descents, efficient propulsion, and the ability to maintain position even during task loading.
Situational & Team Awareness: Strengthen communication, problem-solving, and team protocols to ensure coordinated responses during complex CCR dives.
THE RAID CCR TEC PATHWAY
RAID’s CCR Tec pathway provides a structured progression for divers transitioning from entry-level CCR skills to advanced mixed-gas rebreather diving. Stuart delivers every course within the pathway, guiding divers from their first CCR-specific decompression procedures all the way to deep trimix capability.
Whether you’re refreshing skills, stepping into decompression CCR, or progressing to normoxic and hypoxic mixed-gas depths, Stuart provides disciplined instruction grounded in operational reality and RAID’s updated technical standards.
Your Structured CCR Progression
Given the UK’s environmental conditions, this is the recommended progression:
CCR Diver 40m, CCR Deco Diver & Limited Trimix 40/45m: Core CCR skills, buoyancy, propulsion, bailout & ascent fundamentals
CCR Normoxic Trimix 60m: Full mixed-gas CCR capability. Deep decompression, gas switching & extended dive durations
CCR Hypoxic Trimix 80/100m: Advanced deep CCR trimix. High-performance bailout planning & long decompression profiles
Why Stuart Specialises in Trimix-Based CCR Training
The UK’s colder water, variable visibility, deeper wreck profiles, and long-range dive conditions make mixed-gas CCR not just beneficial—but the safest and most effective choice for serious technical diving. Stuart’s CCR programs are built around this operational reality. Helium provides clearer decision-making, reduced narcosis, and more stable loop control at depth, all of which are essential when managing a closed-circuit system.
OPEN CIRCUIT TEC
OC Tec courses focus on advanced open-circuit diving skills, including gas planning, decompression, and deep diving techniques for extended range exploration.
